One user with a local printer on our terminal server is having a print issue.

One user with a local printer on our terminal server is having a print issue.

Installed an HP printer a while back on her desktop.

Every morning this user logs into our terminal server, and has to change the defaulted printer back to her local printer.

Which renames its self with (redirection) each time she logs in

The settings on remote desktop connection are checked to use the printer.

I haven't played around in regedit yet. This is on a 2008 r2.

Any advice here would be great I'm tired of running in circles.

Terrible annoying problem

I seem to have a problem with Windows Server 2012R2 remote desktop services. From time to time i cannot manage my servers. We have several Remote desktop farms, one 4 node widows Server 2008 RTM farm, a single Node Windows Server 2012r2 farm and a 6 node Windows Server 2012r2 farm. we have no issue with the Windows Server 2008 RTM farm, but have a lot of issue's with the two other ones. the same issue occurs on both nodes, and the  issue is that i cannot manage them. In server manager i get the following error: "The WinRM client cannot process the request. It cannot determine the content type of the http response from the destination computer. the content type is absent or invalid."

When i try to manage the RD deployments via powershell i get:

PS M:\> Get-RDRemoteApp -ConnectionBroker connectionbroker.domain.group
Get-RDRemoteApp : A Remote Desktop Services deployment does not exist on connectionbroker.domain.group. This operation can be performed after creating a deployment. For information about creating a deployment, run "Get-Help New-RDVirtualDesktopDeployment" or "Get-Help New-RDSessionDeployment". 

last week i had it on the single node, but could manage the node from the other 6 node cluster. Rebooted the single node over the weekend, and the issue was resolved. This morning the issue returned, in which i was unable to manage Remote desktop deployment from all nodes, except one. All published applications are running fine, but cannot the deployment. Rebooting the node resolves the issue for that node.

Have been looking into the issue, where it could be that the kerberos ticket is to large for the logged-on user. However when i log on with a user which is only member of the domain admins, the issue isn't resolved. So think it is not related to where the kerberos, or NTLM authentication issue described here:

http://oyvindnilsen.com/solution-for-powershell-remoting-error-it-cannot-determine-the-content-type-of-the-http-response-from-the-destination-computer/

all servers are fully patched.

Windows Server 2016 RDS forbid or remove powershell for defined usergroup

Hello everybody,

actually i'm trying to forbid or remove powershell.exe for a defined usergroup by using GPO's.

Unfortunately i didn't found an explicit setting for removing it for users and when trying to use AppLocker functionality it seems to damage the startmenu itself. When clicking on the Windows button as a restricted user (and even as non restricted Administrator) the startmenu wasn't displayed.

Does anybody know a working "HowTo" for keeping unauthorized users away from powershell without revoking NTFS permissions on the exe file?

Thanks for your help and kind regards.

Windows Server 2012R2 - Users cannot change an expired password via RDP in Windows, rdesktop Linux works perfectly

I realize this question/issue has been raised before. I have read the following thread regarding this:

https://social.technet.microsoft.com/Forums/office/en-US/677b39dd-8595-4334-b7e5-387c8ff230ec/can-users-change-expired-passwords-via-rdp-to-windows-server-2012-r2-windows-81-if-nla-is?forum=winserverTS

First, the workarounds (which are a poor course of action to take due to lowering security) have not worked for me.

Second, I can confirm that this problem does NOT happen when using another remote desktop client. I have tried 'rdesktop' from a Linux machine, and everything works properly. Users are presented with an option to reset their passwords if expired right in a remote desktop session.

Network Level Authentication is disabled. Given that another operating system (and RDP application) does not have this problem, a registry 'hack' should be unnecessary to resolve this. Has there been any acknowledgement from Microsoft of this problem and is there a fix in the works?

RDS 2016 RemoteApp not going correctly fullscreen

Hi all.

Im testing out RDS 2016, so far its been very nice and performance is great.

But im having a wierd issue when trying to run RemoteAPPs in maximized windows (fullscreen)

It sort of looks like the window is in a incorrect placement. The top and leftmost part of the window is sort of moved out 5-6 pixels when running fullscreen. The buttom part of the window is also below the processbar of the workstation im using.

On my client i am running 2560x1440 and im not sure if that is the issue, but it just seems strange.

Have anyone experienced anything similar, and do you have a solution for the issue?

I have no issues copying and pasting to and from my PC and RDSH. Only issue is that I have to manually refresh to see the pasted item/s. I remember running into the same issue on 2012 R2 but I am re-building our environment in 2016 and unfortunately I did not take notes on what I did last time. Does anybody have any suggestions?

Windows 2012 R2, the issue suddenly happens, RDP no longer working. I checked all the following below and they are all good.

1. Registry key - RDP is enabled

2. GPO (local and domain) - not settings for RDP

3. RDP services are running

4. RDP session is enable in Windows

5. Port 3389 is open and listening

The following RDP tests and failed!

1. RDP by FQDN

2. RDP by its IP

3. Loopback RDP with 127.0.0.1

All three tests above gave the error message shown

What else I can check to fix this? thanks.

Windows server 2016 RDS - Printer driver installation

Double clicking on a print server queue, a regular user can trigger installation of a printer drivers through "point and print".

This shouldn't be allowed. Only administrators should have rights to write (or trigger writing) in C:\Windows\system32\spool\DRIVERS\

At least this was not allowed in W2008 R2 RDS.

Windows server 2016 - Software Restriction Policies - Designated File Types

January 20, 2017, 7:08 am

Hi

After applying a software restriction policy GPO, servermanagerlauncher.exe won't run.

This program is scheduled to run "At logon of any user" (rather Administrators) and it returns the popup error "This file does not have a program associated with it". ???

Any other executable runs fine, in particular ServerManager.exe runs well.

This GPO reset the list of "Designated File Type", in which EXE is present.

This GPO was set (a long time ago for W2008 RDS) to remove LNK (i.e. shortcuts) from the Designated Files Types. So any shortcut can be run from anywhere (i.e user's dekstop), while the real executables (Designated File types) are allowed only from specific locations (Basically C:Windows\ and c: \program files).

What's specific with servermanagerlauncher.exe ?

Authentication Steps for RDS 2012 R2

I am troubleshooting some issues with RDS and the security tools deployed in our environment and would like to ask if anyone can provide details on the authentication steps for a 2012R2 RDS farm.

I have a Web Access, Gateway, Connection Broker and 2 Session Hosts.

I provide credentials to log on to the WA and successfully get the icons for the available apps. When I click on a icon I get a "Do you trust the publisher..." prompt and respond "Connect". I then get prompted for credentials which provide (correctly) and I get "Your credentials did not work..." and asked for the credentials again. When I enter the same credentials the second time the remoteapp opens successfully.

I have reviewed the event logs but can't quite piece together the authentication steps to figure out where and why this fails the first authentication attempt but then passes the second and opens the app.

Does anyone have any docs of links that explain, step by step, the authentication steps involved?

Thanks in advance.

Problems with connecting to RDP over VPN

January 5, 2017, 11:46 pm

Hello

I'm using Windows server 2012 R2 standard, the server is located on an ESXI 6.0.

I did a migration of SBS2008 to Windows Server 2012 with this manual https://blogs.technet.microsoft.com/canitpro/2014/05/27/step-by-step-active-directory-migration-from-windows-server-2008-r2-to-windows-server-2012-r2/

I'm able to setup a PPTP VPN connection to the new server. I'm able to ping to the new server and to the old server aswell, when I'm connected via VPN. But when I want to go to the shares it doesn't work. (Can't find server on IP address) Also the remote desktop doesn't work via VPN. 

I'm able to connect to the old server via RDP and file shares are reachable. I already disabled firewall and endpoint security, still that doesn't seem to resolve the problem.

[Edit]

I narrowed my problem down to the following:

I tracert to the server over the VPN and i get 2 replies:

Tracing route to 172.16.0.251 over a maximum of 30 hops

  1    26 ms    30 ms    35 ms  RDPSERVER [172.16.0.117]
  2    27 ms    32 ms    33 ms  172.16.0.251

When I try to RDP to .251 it doesn't work over VPN, but when I try to RDP to the .117 it does work. And that is the new RDP server.
In other words it is possible to make a RDP connection to the internal interface (the one I see in Routing and remote access), but it doesn't work to the Ethernet0 (with IP address .251)

RDP to the old server works over VPN. But I think the problem is something with the Routing and Remote Access, but I got no idea how to solve it.

If there are other things you need, just ask

Thanks for the feedback

Kind regards

Cannot RDP to servers via hostname, but IP is OK?

We had a major issue today in one of our sites where we could not RDP to server via their hostnames (tried FQDN as well) but when we tried the IPs of the servers it works OK. The times & timezones on all servers were spot on so no issues there. All IP details were as they should be and nothing had changed yesterday or today.

We tried IPCONFIG/FLUSHDNS, IPCONFIG/REGISTERDNS on all servers and nothing fixed the issue. We restarted the domain controllers and still nothing. Tried setting the DNS server IPs to those of domain controllers in other sites and still nothing.

What worked was that we had to reboot each server having the issue and that fixed the problem. Ony thing was that we have around 10 servers, all in production, with the same problem but the other 90 or so servers were not affected!?

Set up Clustered Hyper-V RD Virtualization hosts?

I have a VM running Broker/gateway/RDWeb, which is working fine.  I'd like to add RD Virtualization hosts for full desktop VDI.  I have two servers in a cluster with shared fibre SAN storage, but I can't figure out how to point the RDS environment to use the cluster resource for the RD virtualization host.  If I point the RDS set up to the cluster name/IP for the RD Virtualzation host, it fails.  If I point it to the individual nodes of the cluster, it installed, but this is useless to me as their shared storage is only active on one node at a time.  

How can I get both nodes with RD Virtualization Host roles installed to be clustered in such a way as to have the cluster itself (or a clustered resource) be available as the RD Virtualization host?

RemoteFX + Tablets

January 20, 2017, 3:23 am

Hello,

My project is the following one :  i am working in a security company which sells intrusion-detection and video-surveillance solutions.
One of our clients is having issues with its existing solution because we underestimated the need of the software we implemented.
The software is named "Genetec - Security Center". It is based on a windows server 2012 R2.
The server is perfectly ok, but the client parts is far from being ok.
We sold tablets, which are overused by the software, which cause them to freeze, lose connections to the server, etc. And most of all, they are slow.

The main issue is that, because they are tablets, the graphics are generated by the UC. They  are not designed to support that kind of load and usage.
We have 7 tablets plus the server, all linked to the network with Cat.6 cables on a dedicated Local network.

The solution i am studying is to create a new server, to work aside of the first one, and the new server would be dedicated to RemoteFX which by it, i would use the LAN and make remote sessions to ease the load of the tables by using them only for making remote sessions, the rest would be taken cared of by the new server.

I have to display 6 cameras per screen, resolution : 1080p, for the cameras and the screen resolution of the tablets.

So i have several questions like :

-Is such a solution is a good one? If not, what are my other options?

-Considering the fact that i have 7 tablets to run simultaneoulsy, which would be better?  Create via Hyper-V, one virtual machine per tablet, or could Terminal Server be a better solution, regarding the price, the eased management, etc. ?

Thank you for the advices and/or solutions.

How to set TZ for different RDS users

January 19, 2017, 2:46 pm

I have some apps that are TZ sensitive on our 2012 RDS farm, as such TZ redirection is enabled in group policy.

The issue I have is one particular app requires the user TZ to match the local server which is in AU.  I have users in NY and other US regions using this app and they get TZ errors from the app because their local date differs from the server date.

Because the client redirection is a computer setting in GPO I can't turn off TZ redirection for specific users.  I've tried creating a targeted login script that runs TZUTIL and sets the zone to AUS +10 however I find this is hit and miss, sometimes it works sometimes not or it works the first time but if they reconnect it goes back to their local time. I've also seen it change the TZ to AU time when you first login but then 10 mins later it changes back to the remote clients TZ

Any suggestions how I can overcome this. 

I understand that the config may be mutually exclusive for the apps that require AU time and others that need actual local time but this is OK, the users of the apps are different roles and need one or the other.

Remote Desktop default printers not setting

Our scenario is mac based and we use remote desktop to use windows applications we can't run on them.

There's one problem with printers <g class="gr_ gr_45 gr-alert gr_spell gr_disable_anim_appear ContextualSpelling" data-gr-id="45" id="45">though</g> on their remote desktop login, no one is able to set their own user specific default printer.
You set the default and everything is working fine, till you log off then back on.. what will happen is the printer default is the first printer but then their printer has duplicates installations of it, you can tell this when you right click the printer and it asks which printer you want to change i.e. 
>samsung 1234
>samsung 1234
>samsung 1234

I then have to delete their local profile and get them to log back in again for it to go back to normal, their printer <g class="gr_ gr_32 gr-alert gr_gramm gr_disable_anim_appear Grammar multiReplace" data-gr-id="32" id="32">is then default</g> without multiple installations of the same printer, till they log out and back in.
I have even recreated their profile and given them a new one but it's still the same issue.

Any ideas? GPO is not set for any defaults etc

Might be worth mentioning that we have two servers for active directory logins of rds1 and rds2, it will split the users onto both servers to share the load. If one person is logged into rds1 then the server will redirect them to rds2. We have to delete both profiles on both servers, is there a link issue here because of the two profiles?

W2016 - RemoteFX setup for fluid video rendering and low cpu

Hi,

I noticed that w2016 RDSSH (virtual machine non-hyper-v) will uses twice as much cpu than w2008 r2 when rendering video. That's a big disappointement.

There is a RemoteFX GPO for W2008 R2 to set frame rate and video quality. I had set for a fluid video rendering (i.e. High frame rate and medium video quality). Watching videos is not at all the main purpose of my servers and the service is fair enough w/ w2008 r2.

Is there a similare setup for W2016 ? Or any other tweak to get fluid video and low cpu ? (Network bandwidth is not a problem. All clients are 100Mb/full)
